Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Open Pit Mining Introduction • The usual excavation method with this type of surface mining relies on drilling and blasting followed by shovel excavation (rope or hydraulic) and truck haulage. • Spoil requires extensive transport and spoil heaps are located outside the pit, but as near as possible to minimise transportation. This is the main difference to strip mining • Typical

What Is Surface Mining? Types of Surface Mining

These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.
